HIRAM TAYLOR, OF CINCINNATI, OHIO.

IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 79,279, dated June23,1868.

To all whom it may concern:

Be it known that I, HIRAM TAYLOR, of Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in Lubricators; and I do hereby declare the following to bea sufficiently full, clear, and exact description to enable one skilledin the art to which my invention appertains to make and use it,reference being had to the accompanying -drawin gs, which form a part ofthis specication.

My invention consists, first, in casting around and within the neck of areservoir a metallic collar, for the purpose of connecting saidreservoir to the supporting-stem; second, in combining with theaforesaid collar a threaded bushing or tube, of harder metal, for thereception of the stem; third, in employing within the hollow stem of alubricator a regulating-l rod, provided at its upper end with anenlargement or projection, for the purpose of supporting the said rodout of contact with the journal.

In the drawings, Figure 1 is an elevation of a lubricator, illustratingmy invention. Fig.

2 represents a vertical section thereof.

A may represent. the journal to be lubricated 5 B', its bearing, and Gthe cap. E is a hollow stem, screwed into the cap O, to conduct oil tothe journal. D is a rod to graduate the ilow of oil through the stem E.To allow the oil to ow throughthe stem, the rodv is made somewhatsmaller than the aperture therein, or formed with a flat side. Tosupport the rod out of contact with the journal, it is formed with Vaprojectionor enlargement, d, on its upper end to rest upon the top ofthe hollow stem E.

By means of a number of rods of different sizes, the rapidity of theilow of oil may be varied as desired.

At the upper end of the stem E is a screw, ttin g an internally-threadedtube or bushing, F, which is secured to the neck H of the glass globe Gby a collar, I, of fusible metal, compounded substantially as follows:Tin, two pounds; lead, one pound; bismuth, about one ounce; antimony,about two ounces, The purpose of the bismuth is to make the molten metaliow more freely. The object of the antimony is to render it more hardyand irm when set.

Having melted the tin, lead, and bismuth together, I add antimony untilthe molten mass acquires a bright, clear luster. For this purpose it isbelieved that to take about the proportionate quantity named above,grooves hin the glass H adapt it to firmly retain the soft-metal band I.For the same purpose any suitable inequalities may be formed on theperiphery of the tube or bushing F. f

The band or collar I is cast around and within the neck H, and, eitherwith or without the threaded bushing F, constitutes an airtight andstrong attachment for the supportin g-steni E.

A washer, J, may be employed to form an air-tight joint between the stemE and collar I, when the former is screwed into the latter, as hereinrepresented.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A metallic band or collar, I, cast around and within the neck of thereservoir G, for the purpose of attaching the supporting-stem E thereto,as specified.

2. In combination with the band or collar I, of soft or fusible metal,applied as set forth, the threaded tube or bushing F, of harder metal,for the reception of a screw on the upper end of the stem E.

3. The rod D, formed with a projection'or I enlargement, d, on its upperend, to support it out of contact with the journal, substantially asdescribed. 4

To the above specification of my improvements in attaching glass globesof lubricators to their hard metallic stems, and regulating the flow ofoil therefrom, I have signed my hand this 28th day of March, A. D. 1868.

H. TAYLOR.
